This calendar is a non-exhaustive list of forecasted river events held on the tidal Thames between the Estuary and Teddington likely to have an effect on navigation.

Mariners are also advised that there may be other events of which the PLA have not been informed.

Events that require a river closure or local traffic control will be announced by Notices to Mariners, in addition to being displayed on this calendar.

Vessels in these areas around times indicated are to proceed with caution, with special attention to their wash and should avoid obstructing the races or stopping in the area adjacent to the race course.

Latest information on the events may be obtained from the Harbour Service Launch, call sign Thames Patrol, or from London VTS on the port working frequency.

Please note that events on the tidal Thames require Harbour Master consent – if you wish to organise an event on the river, please refer to our event organiser guidance page.
